Species

Celmisia walkeri

Etymology

Celmisia: Apparently named after Kelmis, one of Idaean Dactyls, a group of skilled mythical beings associated with the Mother Goddess Rhea in Greek mythology. Kelmis, whose name means ‘casting’, was a blacksmith and childhood friend of Zeus, son of Rhea and later king of the gods. In Ovid’s ‘Metamorphoses’, Kelmis is described as offending Zeus who turned him into adamant so he was as hard as a tempered blade

Common Name(s)

Walker's mountain daisy

Features

Sprawling, sometimes lianoid, shrub with main stems up to ± 2 m long and 5-15 mm diameter; branches and branchlets stout, woody, ± invested by persistent leaf-sheaths and leaf-remnants. Leaves slightly viscid, numerous, densely imbricated along branchlets. Lamina 20-50 × 3-5 mm, erect but becoming patent and finally reflexed; narrow-oblong to narrowly obovate-oblong, slightly narrowed to sheath, coriaceous; upper surface glabrous, ± viscid, grooved, midrib impressed; lower surface clad in soft white appressed tomentum, midrib evident; apex ± acute; margins flat, rather obscurely toothed; sheath pale, slightly wider than lamina at apex, 15 × 4 mm, pale brown, thinly coriaceous. Scape 100-200 mm long, slender, ± glandular-pubescent; bracts several, linear-subulate, up to 20 mm long. Capitula 20-40 mm diameter; involucral bracts linear, 6-8 mm long, pale, ± glandular-pubescent to glabrous, margins ciliolate, midrib distinct. Ray-florets numerous; claw ± compressed, 6 mm long, white; limb 6 mm long, elliptic-oblong. Disk-florets 6-7 mm long, narrow-funnelform; teeth minute, triangular. Achenes c. 5 mm long, subcompressed-cylindric; ribs rather obscure, with minute ascending hairs. Pappus of sordid-white minutely barbellate hairs up to ± 6 mm long

Similar Taxa

One of a small group of subshrub Celmisia which includes C. brevifolia, C. gibbsii, C. rupestris, C. lateralis and C. ramulosa. From these species C. walkeri is distinguished by the scape which is 100-200 mm long; by the lamina which is 20-50 x 3-5 mm, and by the leaf undersides which is clad in soft white tomentum.

Flowering

October - February

Propagation Technique

Difficult. Best grown from fresh seed but can be grown from cuttings. Should be planted in a free draining, moist soil. Excellent in a pot in an alpine house, or planted in a south-facing rockery. Dislikes humidity and will not tolerate drying out.
